Star-crossed lovers?

An astrologer.

Fate, Fortune, and the influence of the stars; how seriously
did Shakespeare's audience take them? As in so many things,
the plays offer a dynamic debate on the subject. There was
certainly a widespread belief in astrology, though
Shakespeare's own views, as usual, are impossible to pin
down.

Then there is Queen Mab, the magical creation of Mercutio. Is
this wonderful poetic outburst a simple decoration, or does
it in some way echo the movement of the play from a comic to
a darker world?
